Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \

with top-most commit 41c169d9ae2c890552044e129d101995b62c8a02

Merge branch 'pm-avs'

on top of commit defb53a7c790f9e37a765de8a5d830ed15e2055b

Merge tag 'pnp-5.10-rc1' of

to receive more power management updates for 5.10-rc1.

First of all, the adaptive voltage scaling (AVS) drivers go to new
platform-specific locations as planned (this part was reported to
have merge conflicts against the new arm-soc updates in linux-next).

In addition to that, there are some fixes (intel_idle, intel_pstate,
RAPL, acpi_cpufreq), the addition of on/off notifiers and idle state
accounting support to the generic power domains (genpd) code and some
janitorial changes all over.


- Move the AVS drivers to new platform-specific locations and get
rid of the drivers/power/avs directory (Ulf Hansson).

- Add on/off notifiers and idle state accounting support to the
generic power domains (genpd) framework (Ulf Hansson, Lina Iyer).

- Ulf will maintain the PM domain part of cpuidle-psci (Ulf Hansson).

- Make intel_idle disregard ACPI _CST if it cannot use the data
returned by that method (Mel Gorman).

- Modify intel_pstate to avoid leaving useless sysfs directory
structure behind if it cannot be registered (Chen Yu).

- Fix domain detection in the RAPL power capping driver and prevent
it from failing to enumerate the Psys RAPL domain (Zhang Rui).

- Allow acpi-cpufreq to use ACPI _PSD information with Family 19 and
later AMD chips (Wei Huang).

- Update the driver assumptions comment in intel_idle and fix a
kerneldoc comment in the runtime PM framework (Alexander Monakov,
Bean Huo).

- Avoid unnecessary resets of the cached frequency in the schedutil
cpufreq governor to reduce overhead (Wei Wang).

- Clean up the cpufreq core a bit (Viresh Kumar).

- Make assorted minor janitorial changes (Daniel Lezcano, Geert
Uytterhoeven, Hubert Jasudowicz, Tom Rix).

- Clean up and optimize the cpupower utility somewhat (Colin Ian
King, Martin Kaistra).
